Mz8: dark, bias, and frame thermal

Ieri volevo provare ad elaborare una serie di foto di M31 da 600 secondi acquisite con la Mz8 che, salvo errori, produce un delta termico di -30°C, senza avere i dark corrispondenti.

Ho cosi' provato ad usare l'apposita funzione "ottimizza dark frame" di Astroart.
Per farlo bisogna pero' preventivamente sottrarre il bias dall'immagine e dal dark di cui si dispone.

Ho notato quanto segue:


Dark


Bias


Thermal frame

!?! But

and 'so' essential to have always taken the dark at the temperature and duration of image acquisition? Lucio

Damn! You
was right!
The huge difference was due to the different stretch of the images.
After subtracting the resulting image is more 'but only until dark' on Astroart, do not click on the bottom bar of the photo. After
becomes so ':

New Moon - September 2010 - 4-12/9/2010

For the new moon of September I was taken a week off in the hope of being able to do something.

From the weather initially seemed to be the best time on the weekend of 4-6.
Unfortunately, as often happens the weather more 'correct those were general and not detailed to the desired location.
fact both Saturday and Sunday night I arrived on time in the Air (low), that left me deep in the fog (at least until the time that I decided to give up .. the approximately 22:30-23).

Not to waste time on Monday 'I decided to go home, hoping for an improvement for the following weekend.

Fortunately things have improved and gived 'night I found at Balma with Lucio. Unfortunately

Thursday 'after a couple of hours we were "working" and 'the mist came again, while Friday' time and 'was perfect: crisp and perfectly clear.

Friday 'came Chiara, and Giancarlo, and Saturday I'll be with Salvatore, James, and more' late David.

For my part I had to try the new electronics to drive the telescope, the Gemini Pulsar2 the Hungarian company.

For the moment, being content only to check alignment procedures, goto autoguide, everything seems perfect, with the simplification, compared to previously used DA1, not having to set the keyboard drive from the PC or the relay chamber guide which often forcing me to close the acquisition program because of being forgot to do so.

The group photo will be, as usual, soon be available on my personal site, but here I attach only the astronomical photos.

Following the tests done previously, I used the program for the acquisition of CcdCap MagZero for tracking and Maxim. How
from tests carried out, not 'see any lines on individual poses.



Saturday evening, among other pictures, I tried the Helix nebula.
Sum of 29 exposures of 300 seconds, dark and flat, MagZero Mz8 Fsq85 up.

I spent the afternoon and evening yesterday trying to process the images taken in last weekend.
I am more and more 'account to be truly prevented capacity as' computing.
Despite two "courses" made by David and Leonard have not been able to learn how to draw pictures for educational purposes!
E 'prorpio true Leo: I have a Ferrari in the ass but the license for the tricycle!

However I was really amazed by what I took out the Atik 314L + attached to C8 f / 6,3 ..... without guidance, without dark, no flat (without add collimation seen the state of the stars), maybe just enough to fire right (thanks to the blessed Bahtinov mask), the Great Nebula of Orion.

I did just for fun only 150 exposures of 10 second in the state described above, then processed with Maxim, with manual alignment sigma clip, followed by only two stretch logarithmic / linear!

Here is what I 'letteralemte turned out despite the severe limitations (ps: among other things did not really understand where they are over ... so if someone was' kind enough to help me .... richettienrico snails tin.it):



And with this more 'stature color:




September 20, 2010



For M45 that I have 11 frames of 300 seconds' the usual Drak, Flat and Bias (again just this last Sunday with l'ausilio di CCdCap) ho tentato una nuova successione degli "eventi" procedendo in questo modo:
Calibrazione e allineamento con Maxim;
Somma e conversione a colori con Astroart;
Stretch logaritimici/lineari con Maxim (2);
Saturazione e salvataggio 8bit con Astroart.
Ps: o e' successo qualcosa di strano in fase di elaborazione oppure ho beccato un Ufo. Lo vedete anche Voi?



Con M31 (di cui ho 12 frame da 300 secondi e 7 da 600 secondi) la cosa non ha funzionato ed ho dovuto procedere in altro modo:
Calibrazione e conversione a colori con Astroart;
Allineamento con Maxim (una gran fatica... il pc non riesce ad allineare tutte le immagini convertite color);
Sum with Astroart;
Stretch logaritimici / linear Maxim (2);
saturation, unsharp mask with 8bit and rescue Astroart.


With M33 I have adopted the same system, adding 15 frames of 300 seconds, but content with a single stretch logarithmic / linear.


And this' for a bit more saturated colors.
